LOCTITE® 3090™ is a two-component, fast-curing cyanoacrylate adhesive formulated with ethyl cyanoacrylate. It combines high strength with gap-filling capability up to 5 mm, providing reliable bonding across a wide variety of substrates such as plastics, metals, rubbers, and porous materials. The thixotropic gel consistency prevents flow on vertical surfaces, while the system cures quickly after mixing, achieving handling strength in minutes and full cure within 24 hours.
Bonding plastics, rubbers, and metals.
Gap-filling applications up to 5 mm.
Bonding porous materials like wood, leather, fabric, paper, and chipboard.
Assembly operations where excess adhesive must fully cure.
Suitable for vertical or overhead bonding due to its gel-like consistency.
